Re. password... we landed on requiring a password to create the room to let you retain the "HOST" status. E.g., if you disconnect and go back ... need password to authenticate as HOST so that you won't lose your room to the first stranger that finds it empty
But all rooms are open. Password is just a "Recovery password". I will update now the description text to this
Also seems to require a password to host a room (can't just leave it open?)
